Welcome to Windows 7 Forums. Our forum is dedicated to helping you find support and solutions for any problems regarding your Windows 7 PC be it Dell, HP, Acer, Asus or a custom build. We also provide an extensive Windows 7 tutorial section that covers a wide range of tips and tricks.

The first thing I would do is to boot into BIOS and see if the drive is recognized there. If it isn't, open the case and check the drive connections and make sure that they haven't worked their way loose from vibration. While you're inside the case, put your finger on the drive (on the drive's case. Don't touch the drive electronics.) and turn on the power switch. As the machine powers up, you should feel a little bit of vibration and movement from inside the drive. If you don't feel anything, the drive might be seized up.

It isn't unusual for a drive's bearings to suddenly seize up and stop spinning. No spin, no data, no drive.

I had a HDD disappear on me once. It turned out that, for some odd reason, it lost its drive letter. I found it when I was advised by someone here to go into Disk Management and put the drive letter back in. That drive is still in service without a hitch since then.
